I have had good luck with going up the food chain. The people higher up are usually more professional and much easier to work with. Keep going up until you get it resolved. If you still don't get it resolved after a couple levels, then type up a letter, sign it and and mail direct to the CEO. They can take a couple of weeks to get back to you, but they will. And you will most likely get the results you want. Be sure to put as much information, documenting phone calls, etc. When I have been hassled by a fault by a company, then I have asked for additional compensation. Be clear and state what you want.
